All praises are for Allah Subhanahu wa Ta’ala Who created the heavens and earth and all that is between them and is holding the skies without any pillars. Who is Blessed , in Whose hands is Dominion, Who has Power over all things ,Who created Death and Life, Who is the Exalted in Might, Oft-Forgiving. He sent the last testament which is such that no falsehood can approach it from before or behind it: It is sent down by One Full of Wisdom, Worthy of all Praise. Praise be to Allah, Who hath sent to His Servant the Book, and hath allowed therein no Crookedness: Allah is the Protector of those who have faith: from the depths of darkness He will lead them forth into light. So, what is in the depths of darkness and what gets enlightenment? In this book a humble effort has been made to answer this question. It is the Qalb , the real instrument for understanding the Qura’n . I hope this booklet will prove quite useful to the seekers of the truth by the grace of Almighty Allah and I pray to Allah Ta’ala to accept this little work and make it a means of salvation for me in the hereafter.
